Trivia

What makes it special

Frozen world. A deep-frozen world far from its star's warmth.

Could we get there?

Verdict. Hopelessly far for any craft humanity can build today.

Getting there

Aboard Voyager 1. ≈ 256.3 thousand years at Voyager 1's speed (17 km/s).
Fastest probe ever. ≈ 22.8 thousand years even at the Parker Solar Probe's 192 km/s.
At 10% light speed. ≈ 146 years in a starship at a tenth of light speed.
Distance. 14.6 light-years from Earth.

Look-back time

Look-back time. The light you'd see left around the year 2011.

Saying hello

Say hello. A radio message and its reply would take 29.2 years round-trip.

Standing on it

A year here. A full year lasts about 2.1 Earth years.

By the numbers

Size. About 9.6× the width of Earth.
Volume. About 885 Earths could fit inside it.
Mass. Roughly 66.7× Earth's mass — about 0.2 Jupiters.
Your weight. You'd weigh about 0.7× your Earth weight standing here.
Density. Less dense than water — drop it in a big enough ocean and it would float.
Temperature. A frigid -207°C — colder than dry ice.

How we found it

Discovery. Found by Multiple Observatories using the radial velocity method.

About GJ 9066 c

GJ 9066 c is an uncommon exoplanet. It lies about 14.6 light-years from Earth, has an equilibrium temperature near 66 K, spans roughly 9.6 Earth radii and weighs about 66.74 Earth masses.

A deep-frozen world far from its star's warmth.

How to see it

Like any astronomical target, GJ 9066 c is best seen from a dark site away from city lights, and when it is above the horizon depends on your latitude and the time of year. The visibility panel above works out tonight's viewing window for your saved location.

Why GJ 9066 c is an uncommon exoplanet

GJ 9066 c scores 29 points on Spacedle's rarity scale, which places it in the uncommon tier. Another 4 points would lift it into a rarer tier.

That score comes from 4 science badges — Confirmed exoplanet, Gas giant, Frozen world and Nearby (<25 ly) — each earned for a real, measurable property of the object. Rarity on Spacedle is never random: the more remarkable an object's astrophysics, the more badges it collects, the higher it scores, and the rarer it ranks.
